This model was built from a Kato SD 40. The dynamic brake blister has been removed to represent an as delivered nondynamic CNW SD 40. The unit was detailed with such items as a DW plow, eyebolts, cab vent, and MU hoses. Also, I replaced the Kato grab irons with wire ones from Detail Associates. Painting involved using Des Plaines Hobbies Scalecoat II CNW Yellow for the old yellow and Modelflex CNW green. The underframe was finished with Testors Modelmaster Acryl semigloss black. The decals are from Microscale. The overcoat is half Testor's glosscoat and half Testor's Dullcoat thinned with lacquer thinner.
